At the other end a drill 10is made, the body 15 formed While that body 15 bemg cast which opens theintake end of the sleeve 6 and thus permits water to flow horizontallythrough the sleeve from one end to the other. The plastic material ofthe body 1 is thus substantially protected against contact with the tapwater and the body will thus not be eroded as quickly to protect theinner hollow portion of the sleeve and as if the body Ware not protectedSince the sleeve 6 g z igz g g gg f gf g filhng Wlth the plastlc isrigidly fixed in position, it is relatively simple to form Anotherobjectyof my invnfion is to provide a novel the hole 9 by straight drilland to cut the hole 10 with sleeve forming the water conduit in a waterfaucet, this 635 z g ffifig sleeve bein constructed so that it can bereadil drilled at both ends after the faucet body is cast thus provid-An mtegrany cast cqndmt for a .Valve mcludmg a ing an open conduit fromthe water intake to th water molded plastlc body havmg spaclgd Hltakeand Outlet outlet of the faucet ports therein, a sleeve embedded 1n saidbody and ex- Still another object is to provide a novel integrally jffil igfi igg i gi gfii E32 as recited in cast sleeve or conduit which issimple in construction, in- 3 clain 1 g sleyeve being closed at bothends when a expensive to manufacture, and which can be readily placedmolded in the body, and drmable at both closed ends in the mold prior tothe casting of the faucet body.
